*For cases of extreme metal + mineral buildup, process up to 10 minutes, then proceed with the instructions.

**For best results, we recommend to use K18 chelator before every service. If not using K18 chelator, lightly dampen hair with water (do not saturate) before applying K18 PRO mist.

  • DO clarify before K18 if your client is a heavy product user (demineralize for mineral + metal buildup)
  • DO apply a generous amount of the PRO mist, Don’t overdo it with the mask—less is more
  • DO apply K18 mask on clean, damp hair (think about 65% wet)
  • DON’T use conditioner before applying K18 mask (you can apply after the 4 min but most find they don’t need it)
  • DON’T rinse it out
  • DON’T mix into your bleach or color
  • DON’T increase your bleach volume or alter your typical color formula

got questions?

Get started here

The K18REPAIR™ service works by reversing damage before and after services for stronger, more resilient hair. K18 PRO mist restores chemically damaged hair before services, making hair more resilient for salon transformations. Use before services for a stronger foundation and to help prevent damage during services. Follow with the K18 PRO mask to reverse damage done during services and to soften, smooth, and condition hair.

The K18PEPTIDE™ powering both formulas reverses damage from bleach* + color*, chemical services*, and heat* in 4 minutes. It works by reconnecting breaks in the hair fiber along both the length (keratin chains) and the width (disulfide bonds) for holistic hair renewal.

*Disclaimers

K18 is engineered to work with every hair type, in every service, and with every routine.

We recommend misting hair with water before using the PRO mist to swell the cuticle layers and open up the hair fiber, allowing for maximum penetration of the peptide-powered PRO mist into the innermost layers of hair. In the same way a damp sponge absorbs more water, damp hair absorbs K18PEPTIDE™.

If you’re using the PEPTIDE PREP™ pro chelating hair complex, there’s no need to mist the hair with water before using the PRO mist.

K18 PRO mist will not interfere with toner or final color. In clinical testing, we’ve found that color lasts longer + fades slower* when paired with mask usage at home.

*Disclaimers

K18 PRO mist + mask are not protein treatments, our biomimetic peptide naturally mimics the amino acid sequences in keratin to rebuild bonds broken by bleach, color, and chemical service damage. If your clients are experiencing dry, brittle hair, use PEPTIDE PREP™ detox shampoo pre-K18 mask to remove buildup.

Amazing!

I have always struggled with my 3B curly hair being frizzy and dry due to consistent dying. I’ve noticed a significant improvement in the texture. My hair feels like hair again with the moisture helped my curl pattern shine! I’ve gotten TONS of compliments on my hair asking if it was natural after I started using it!
